Python: Methods inside a method in a class - 


import numpy np  class y:     def __init__(self):         return none      def f(self,x):         return x      def g(self,x):         return f(x)**2 y=y() print y.g(3)

i know above code give error, somehow want following, there modification do?

the reason doesn't work because have f(x)**2 instead of self.f(x)**2. make change , it'll work perfectly.
